When changing so that the client passes its stdout and stderr as well as stdin up to the server, I forgot one essential point - the tmux server could now be both the producer and consumer. This happens when tmux is run inside tmux, as well as when piping tmux commands together. So, using stdio(3) was a bad idea - if sufficient data was written, this could block in write(2). When that happened and the server was both producer and consumer, it deadlocks. Change to use libevent bufferevents for the client stdin, stdout and stderr instead. This is trivial enough for output but requires a callback mechanism to trigger when stdin is finished. This relies on the underlying polling mechanism for libevent to work with whatever devices to which the user could redirect stdin, stdout or stderr, hence the change to use poll(2) over kqueue(2) for tmux.

Return the command client return code with MSG_EXIT now that MSG_ERROR and MSG_PRINT are unused. New clients should be compatible with old tmux servers but vice versa may print an error.

Get rid of the ugly CMD_CHFLAG macro and use a const string (eg "dDU") in the command entry structs and a couple of functions to check/set the flags.

Add a flag for jobs that shouldn't be freed after they've died and use it for status jobs, then only kill those jobs when status-left, status-right or set-titles-string is changed. Fixes problems with changing options from inside #().

Convert if-shell over to the background job framework as well.

Use KEYC_NONE constant instead of 0 on init.

Make all messages sent between the client and server fixed size. This is the first of two changes to make the protocol more resilient and less sensitive to other changes in the code, particularly with commands. The client now packs argv into a buffer and sends it to the server for parsing, rather than doing it itself and sending the parsed command data. As a side-effect this also removes a lot of now-unused command marshalling code. Mixing a server without this change and a client with or vice versa will cause tmux to hang or crash, please ensure that tmux is entirely killed before upgrading.
2009-07-14Having fixed flags for single-character getopt options is a bit hard toNicholas Marriott
maintain and is only going to get worse as more are used. So instead, add a new uint64_t member to cmd_entry which is a bitmask of upper and lowercase options accepted by the command. This means new single character options can be used without the need to add it explicitly to the list.

2009-07-09New command, if-shell (alias if). Executes the tmux command in the secondNicholas Marriott
argument if the shell command in the first succeeds, for example: if "[ -e ~/.tmux.conf.alt ]" "source .tmux.conf.alt" Written by Tiago Cunha, many thanks.
